In Germany the president is limited to two 5 year terms. Neither the president nor the chancellor are not elected directly, but by a majority of the members of parliament. This majority can shift during one election period if coalitions change. This could also lead to a new chancellor without a new election.

The president is elected by the Bundesversammlung[1] which consists not only of members of the parliament but also of an equal amount of representatives of the states.
